The Basic Properties and Purposes of a Geothermal Heat Pump

What pretty much all homeowners say they appreciate best about a geothermal heating and cooling system is that it has almost no moving parts. There’s just that much less that can go haywire– that much less to maintain. And that alone goes far in reducing the overall energy costs of Van Buren homeowners who’ve gone geothermal.

 

Still, the system isn’t free of all moving parts. Most of them are found in its most essential component, too: the geothermal heat pump.

This is the engine that drives the system. Its task is to transfer heat. And it transfers heat either from the ground into your house or from your house into the ground, depending on the climate30. As such, it’s a furnace and an air conditioner integrated into one compact package.

Water – or an antifreeze solution – is the medium by which the heat pump transfers heat. This liquid circulates through underground loops of pipe that are attached to the above-ground heat pump. During heating season the liquid draws heat from the ground, the heat pump draws the warm liquid up into refrigerant coils, and the heat is then is conveyed throughout a home by way of either a forced air or a hydronic system. During cooling season the exact opposite happens: the pump draws heat from your home and transfers it underground through those same buried loops. Oh, and somewhere along the way, more than a few geothermal systems also produce domestic hot water.

The basic distinction between a geothermal heat pump and a ordinary furnace is that a heat pump doesn’t set fuel burning to generate heat. No, indeed, it takes heat that already exists and simply moves it around. That naturally makes it a much more efficient heating and cooling system. Recognize this, too: underground temperatures almost always hold at around 50º F through the year. Result? A geothermal heating and cooling system uses substantially less energy to cool your home than standard air conditioners.
